IMP MAY BE WIRED AS EITHER 2 WIRE OR 3 WIRE, GIVING THE FEATURES BELOW
2-wire configuration: 
 RS232 (RJ11 port) connection for diagnostics and software updates 

4 digit LCD display 

4 button keypad for parameter entry 

Power consumption: 3.5 -22mA 

 Passive 4-20mA output
3-wire configuration (additional to 2-wire): 
 Backlit LCD display 

0-10V analogue output 

2 relays: single pole two way, 1A 30VDC/AC 

Power consumption with relays energised <60mA (less12mA/relay not energised) 

Active and passive 4-20mA outputs 
2-wire I.S. version: 
 Intrinsically safe to ATEX EEx ia IIC T4 and IECEx. NB: I.S. IMP is identified by black cap to housing instead of green. Does not include RS232 interface. 
PC Interface IMP P C 
 All parameters can be accessed and changed through IMP PC software. Echo traces may be viewed on screen. NB: IMP I.S. does not offer this feature.
