L0MX0101 Pempek OBP Proportional Solenoid Module Ex ib Intrinsically Safe I/O  Namur Inputs Resolvers Type A

The Pempek OBP Mining PLC I.S. I/O Solenoid Driver Module provides intrinsically safe (Group I Ex ib) input and output resources in a single, compact unit.

A unique fibre-optic communications interface means that the module, and dedicated IS power supply, can be conveniently segregated into its, isolated zone.

The fibre-optic link between the module and an Pempek OBP processor module provides real-time control and monitoring of all I/O points.

This solution is ideal for mobile mining equipment where limited installation space must be achieved.

Uniquely keyed typed connectors to prevent incorrect machine installation.

The module is Dual Pempek OBP Type which complies with AS/NZS 4240 standard.

As per standard, every output includes two switches A&B in series with monitoring feedbacks from both.

Extra safety is achieved by using two potted boards each includes main and watchdog processors monitoring the correctness of executed main software code.
