PL16DI220 - 16 Digital Input Module (220VAC)

The PL16DI220 module is a 16 channel digital input module. The inputs are isolated from the logic by bi-directional opto-couplers. The inputs are divided into 2 isolated groups of 8 inputs each. The inputs are designed for 220VAC input voltages.

The counters operate in three modes.

In mode 0: All the counters are disabled.

In mode 1: The counters are 32 bit counters allowing a count value from 0 to 4294967295. The count value can be cleared by writing a zero to the associated registers or preset to any other value using the same method.

In mode 2: The inputs are connected as up/down counters. Input 1 will increment counter 1 whilst input 2 decrements counter1. In the same way, inputs 3&4 operate counter 2, inputs 5&6 operate counter 3 and inputs 7&8 operate counter 4,etc.

Note: The count values are not battery backed-up and will be lost if power is turned off.
