4 MSR300 Modules: Details
4.1
MSR310 Base Module
Functions:
System control, safety and auxiliary output contacts, supervision of
bus-connected input and output modules.
Auxiliary outputs: 3 solid-state switch outputs for signaling the states of output
groups.
Serial data interface: two RS232 ports (bi-directional and uni-directional).
Selectable start mode: Monitored (manual) or automatic.
The MSR310 has independent feedback loops for each output group.
There are no safety inputs or outputs on this module.
The MSR310 Base Module has three microprocessors: for redundancy and supervision of
I/O modules. Comprehensive diagnostic information is available via two-color LED
indicators, auxiliary solid-state switch outputs and the serial data interface.
