PM800 options
The PM800 can be fitted with 2 optional modules, unless otherwise indicated
(1)
PM8M22 module
2 digital outputs (relays) for control or alarms
2 digital inputs for position monitoring
PM8M26 module
2 digital outputs (relays) for control or alarms
6 digital inputs for position monitoring or pulse counting
This module includes a 24 V DC power supply that can be used to bias the digital inputs
PM8M2222 module
2 digital outputs (relays) for control or alarms
2 digital inputs for position monitoring or pulse counting
2 analog outputs 4-20 mA
2 analog inputs 0-5 V or 4-20 mA
(1) It is not possible to mount two PM8M22 modules. If the supply voltage of the PM800 is less
than 208 V, only one PM8M2222 module can be mounted.
