Microprocessor-Controlled Electro-Pneumatic Regulator ITV2000 EASY PROGRAMMING GUIDE

Maximum load current: 30mA The NPN and PNP digital monitor outputs can be set to function in one of three different ways: comparator mode hysteresis mode self-diagnostic mode when P1<P2 when P1>=P2 when P1=P2=0 The output is on whenever the outlet pressure is greater than P1 but less than P2. The output comes on once the outlet pressure reaches P1.
