Core functions and features

(1) Control function

Speed control: Supports input from MPU (100-25000Hz) and proximity probe (0.5-25000Hz), with an accuracy of 0.03%

Analog control: 8 channels of 4-20mA analog inputs (supporting two-wire/three wire sensors), 4 channels of 4-20mA analog outputs (accuracy 0.2%)

Actuator driver: 2-channel PWM output (4.88kHz), supports single coil/double coil actuators, configurable jitter current (25Hz)

Discrete control: 24 discrete inputs (including 4 preset functions: emergency stop/reset/speed up/down), 12 relay outputs (including 2 dedicated outputs: stop/alarm)

(2) Redundancy and Fault Protection

The third mock examination Redundancy (TMR): three CPU modules work in parallel, two out of three signals vote, and single module failure does not affect system operation

Potential Fault Detection (LFD): Relay outputs are configured in series parallel with 6 relays, periodically detecting contact status to avoid potential fault accumulation

Fault safety state: When the I/O Lock function is triggered, the discrete output loses power and the analog output returns to zero, ensuring equipment safety

Redundant power supply: load sharing of two main power modules, seamless takeover of the other module in case of single power failure
