Alternatively, it is possible to order the OM1 as a separate kit and install it in the basic
actuator in the factory or in the field.
The OM1 is an optional module suitable to accomplish the following EPI2 actuator
additional functionalities:
• Positioner with analog position input 4 - 20 mA or 0 - 10 V DC optocoupled
• Analog output position transmitter 4 - 20 mA or 0 - 10 V DC optocoupled
• Monitor relay remote indication for:
— loss of power
— stop by torque out of limit
— direction failure
— over-temperature
— position sensor alarm
— valve jammed
— hardware malfunction
— alarm on local control panel (if present)
— stroke failure
• Blinker/Local selector relay remote indication
• 4 additional SPST output contacts to be set independently at 12.5% intervals along
the stroke. Contacts are congurable (make or break)
• Optional Bluetooth connection feature
