No analog input/outputs, no encoder interface (different from D137-001-010) Communication configuration

Internal bus: E-BUS dedicated high-speed bus, with a rate of 10 Mbps. Up to 8 modules of the same series D137 can be connected in series with the main controller.

Auxiliary interface: 1 RS232 debugging serial port. No onboard EtherCAT or Profibus external buses. Cannot independently form a networked upper-level PLC.

Interface and communication configuration

Double-layer green spring plug-and-unplug terminals on top and bottom, with digital input wiring on the top layer and digital output wiring on the bottom layer; side snap-type E-BUS bus port. Modules can be cascaded by connecting end to end without the need for external communication cables. Core function

Expand the main control switch quantity points, collect passive/active switch signals such as travel limit, pressure switch, equipment readiness, and fault alarm;

Output points drive intermediate relays, indicator lights, and small electromagnetic directional valves to achieve logic control for equipment start/stop and oil circuit connection/disconnection;

The full-channel photoelectric isolation of input and output ensures isolation from surge interference caused by on-site frequency converters and hydraulic solenoid valves;

The module has built-in channel fault self-check, and real-time upload of short-circuit and overcurrent points to D136 main control and record fault codes;

The MACS programming software uniformly configures addressing, and the points are seamlessly connected with the main control program for programming. Applicable scenarios

Expansion of EH speed control system switch points for turbine units, limit collection for fatigue testing machines for automotive components, logic control for aviation actuator test benches, interlock control for hydraulic press equipment, and expansion of switch quantities for small and medium-sized material testing equipment.

Instructions for Installation and Maintenance

Installed in the dry area of the control cabinet, away from locations with hydraulic oil mist and water vapor splashing;

When driving a large power load, an intermediate relay must be added; direct connection of the load exceeding 0.5A is prohibited;

Check and tighten the connection terminals every six months to check for oxidation and loosening hazards;

The E-BUS bus wiring should avoid large power power cables to reduce electromagnetic interference;

Annual inspection of the 24V power supply voltage, avoiding voltage fluctuations exceeding the rated ±10% range.
