L0LZ0401 Pempek OBP Proportional Solenoid Module Ex ib Intrinsically Safe I/O
The Pempek OBP Mining PLC I.S. I/O Module provides intrinsically safe (Group I Ex ib) input and output resources in a single, compact unit.
A unique fiber-optic communications interface means that the module and dedicated I.S power supply can be conveniently segregated into its isolated zone.
The fiber-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 Type Connectors to prevent incorrect machine installation.
The module is Dual Pempek OBP Type which complies with AS/NZS 4240 standard.Â
As per standard, every output includes two switches A&B in series with monitoring feedbacks from both.Â
Extra safety is achieved by using two potted boards each includes main and watchdog processors monitoring the correctness of executed main software code.Â
