OPMM-1616-XT

OPMM-1616 is a PC/104 digital I/O module designed for industrial applications requiring isolation between the computer and the external signals it is monitoring and controlling.

The OPMM-1616 features 16 opto-isolated digital inputs and 16 relay outputs. Each input has an input range of 0-30VDC. OPMM-1616 can be configured to generate an interrupt when any input changes state. Either or both banks of 8 inputs can be configured for interrupt operation. One 34-pin I/O header is used for the opto-isolated inputs.

The 16 relay outputs are SPDT format (form C). Each relay has 3 contacts: Common, Normally Open, and Normally Closed. For safety and reliability, all relays are at their power-off state at power-up or system reset. Each relay can switch both AC and DC voltages. Two 26-pin I/O headers are used for the relay outputs with 8 relays on each pin header. The relays have long lifetime (10,000,000 operations) and quick actuation time (5ms max operate and release, break before make).

OPMM-1616 provides isolation on its input and output lines. The board will withstand up to 500V DC or AC difference in potential between the I/O lines and the rest of the board’s circuitry. Each input and output channel on Opal-MM-1616 is completely independent and does not share any signal trace with any other channel. Therefore, every channel is isolated from every other channel.
