DI-5 Digital Input Dry Contact – 16-Channel I/O Module

The DI-5 provides 16 dry contact input points in one group with common power for field contacts. A wide range of input devices that are powered by the module can be used such as push buttons, limit switches and electronic proximity switches (these provide dry contact closures). Alternatively inputs can accept 10 to 28 Volts DC from an externally powered input.

Closure of the field contact results in a logic 1 in the status register.

The DI-5 counter module is similar to the DI-1, 16 channel digital input module (the DI-5 also has 16 digital inputs and can act like a DI-1). However, the DI-5 also counts pulses on the first 4 digital inputs. It is able to count up to 10kHz on inputs 1 and 2 and can count up to 255Hz on inputs 3 and 4. Inputs 5 to 16 are normal digital input channels. The pulse total and the pulse rate for each of the first 4 digital inputs are stored in internal registers.
