Failsafe expansion module · motion monitoring of 2 axes · 2 incremental encoder inputs · Sin/Cos, TTL (RS422) or HTL (24 V) · RJ45

Type: speed monitor Axes monitored: 2 Encoder inputs: 2 incremental Signal: Sin/Cos, TTL, HTL Connector: RJ45, 8-pin Safety: PL e / Cat. 4 / SIL CL 3

Overview & Function

The Pilz 773820 (PNOZ ms3p) is a failsafe speed/standstill monitoring expansion module for the PNOZmulti classic configurable safety system. It safely monitors the motion of up to 2 axes via two incremental encoder inputs, supporting Sin/Cos, TTL (RS422) and HTL (24 V) encoder signals. It is used for safe standstill, speed and direction monitoring on presses, drives and axes.

Supplied by SHLY-PLC, an independent industrial-automation distributor. Brand and model are used for identification only; this listing is not affiliated with, sponsored or endorsed by the manufacturer.
