II. Core Functional Characteristics

1. 12-channel KUEP relay exclusive compatibility, high-density efficient layout

Using 12 independent KUEP relay installation positions, specially designed for the Ovation system with KUEP high-power relays, each base integrates 12 relay circuits, balancing point density and single-channel load capacity, compatible with 1C31219G01/G04 driver modules' 12 output channels, one-to-one correspondence, seamless matching.

The base integrates dedicated drive signal conversion circuits, accurately transmitting 24V DC drive signals from 1C31219 series modules to each KUEP relay coil, with low circuit impedance and low signal loss, ensuring the sensitive and reliable operation of relay attraction / disconnection, response delay ≤ 10ms.

Using modular slot installation, KUEP relays can be directly inserted into the corresponding slots of the base, tool-free insertion and fixation, installation and replacement are convenient; the base comes with channel number silk-screen marking (1-12 channels), wiring is clear and not prone to confusion, significantly reducing the probability of errors in on-site debugging and maintenance.

2. Safe drive of strong current loads, multi-level protection high reliability

Each relay circuit is equipped with an independent replaceable fuse (specification 2.0A/250V AC fast fuse), when abnormal conditions such as short circuit or overload occur on the load side, the fuse quickly melts, cutting off the circuit to protect the base, driver module, and relay coil, preventing the expansion of faults; the base side has a fuse compartment, no need to remove the base to replace, maintenance is efficient.

The driver side (module connection end) and the load side (on-site wiring end) adopt a completely electrical isolation design, with a 2500V AC isolation voltage, effectively blocking interference, surges, and fault voltages from entering the control system, ensuring the safe and stable operation of the DCS system; adjacent channels also have isolation design to avoid channel interference and fault crossover.

Compatible KUEP relay contact rated load: AC 250V/10A, DC 30V/10A, can directly drive solenoids, contactors, small motors, pumps, fans, etc. of high-power on-site equipment, without the need to add a relay cabinet, saving installation space and cost; the base wiring terminals adopt a large current crimping design, compatible with 1.5-4mm² copper core cables, wiring is firm, and the conductive performance is stable.

3. Industrial-grade environmental tolerance, strict working conditions compatibility The base body is made of flame-retardant ABS engineering plastic + metal reinforcement frame, featuring high mechanical strength, resistance to vibration and impact, and suitable for industrial vibration environments. It has passed ISA-S71.04 Class G3 pollution level certification, and can withstand corrosive gases, salt fog, and dust environments. It can operate for a long time in extreme conditions such as turbine compartments, outdoor cabinets, and explosion-proof areas.

Operating temperature range: -20℃ to +60℃, storage temperature: -40℃ to +85℃, relative humidity: 5%–95% RH (no condensation), suitable for temperature fluctuating scenarios such as high and low temperature workshops and outdoor cabinets; the base surface is coated with a moisture-proof and rust-proof layer to prevent metal parts from rusting in humid environments and extend service life.

4. Convenient installation and maintenance, easy expansion

The overall size is compact, compatible with Ovation standard rack installation, can be mixed-inserted with other I/O modules (digital input/output, analog input/output) of the 1C series, flexibly constructing a distributed control system; the connection between the base and the driver module adopts Ovation dedicated backplane interface, smooth plugging and unplugging, reliable contact, supports hot-plug module replacement, no need to stop the machine.

Each channel on the front of the base is equipped with an independent status indicator light, corresponding to the relay engagement/disengagement status, the operating status is clear at a glance, no professional tools are required to quickly determine the working condition of the circuit; remote status monitoring is supported, the relay contact status can be uploaded to the Ovation system through the driver module, achieving remote monitoring and fault location.

It is highly compatible, ** fully compatible with 1C31219G01 (standard version) and 1C31219G04 (enhanced version) ** driver modules, new and old models can be directly replaced without modifying wiring and system configuration; it can be mixed deployed with 1C31223G01 (16-channel G2R relay base), and can be configured with 12-channel or 16-channel circuits as needed, flexibly adapting to different point control requirements.
