The 3RG9001-0AH00: This is a digital input module for the AS-Interface bus system, designed for field mounting with IP67 protection — meaning the electronics survive washdown environments typical in food, beverage, or automotive body shops. It provides 4 digital inputs arranged as 2 x 2 (two M12 sockets, each carrying two PNP inputs), accepting 20-30V DC from the AS-Interface bus.
Input specs and wiring
The PNP input circuit switches High at ≥10V and ≥5mA; the Low signal draws ≤1.5mA. Wiring is via M12 screw-type terminals (Y-assignment pinout), supporting 2-, 3-, and 4-wire sensors. The module draws up to 250 mA from the AS-Interface bus total, and the sensor supply is short-circuit and overload protected.
The ID code is 1, and the I/O configuration is 0 — these must match the AS-Interface master's configuration for the module to be recognised on the bus.
