Digital Points: 24 channels of DI / 24 channels of DO

Feedback Interface: 2 channels of SSI / incremental encoder acquisition ports Communication configuration

Local bus: E-BUS (10 MHz high-speed internal bus, directly connected to D136 main controller, up to 8 D137 modules can be connected in series with a single main controller)

Auxiliary serial port: 1 RS232 debugging port, no onboard Profibus/EtherCAT external bus (distinguishing 011 model), unable to independently form a networked upper-level PLC

Interfaces and wiring

Separate upper and lower plug-and-unplug spring terminal blocks, upper end for digital signals, lower end for analog signals; side E-BUS connector terminal blocks enable module cascading, no additional wiring required. Core function

Expand multi-channel sensor acquisition, servo valve drive output, and encoder position feedback for the main control D136 series;

On-board signal filtering circuit to suppress electromagnetic interference caused by hydraulic system oil mist and frequency conversion equipment;

Self-check for faults, short circuit of channels and overvoltage are reported to the main control for alarm in real time;

MACS programming software for unified configuration, IO points can be directly addressed and called within the main control program. Applicable scenarios

Expansion of IO for the turbine electric-hydraulic speed regulation EH system, expansion of test points for the automotive component fatigue testing machine, multi-channel testing platform for material mechanics, and equipment for medium and small-sized hydraulic synchronous forming.

Installation and maintenance instructions

Install in the clean area of the control cabinet, away from the position where hydraulic oil splashes;

Tighten terminal connections every six months, check for oxidation and loosening;

Annual calibration of the zero points of the simulation channels to ensure the accuracy of force control / displacement acquisition;

Avoid laying E-BUS cascading cables parallel to power cables to reduce interference.
