The PMC408 monitors or controls on/off (high/low) status for up to 32 devices. Each channel can be used as an input or output. A unique two-piece board design brings the proven reliability of Acromag’s IndustryPack® (IP) modules to a PMC format. An IP408 module is embedded on a PMC interface card that maintains maximum performance and transparent communication to the host.
Input channels can be configured with interrupts for a change of state or level detection of any bit on up to 8 channels. The TTL input threshold includes hysteresis for increased noise immunity.
In order to ensure safe, reliable control under all conditions, output operation is “fail-safe.” That is, the outputs are always off upon power-up and are automatically cleared following a software reset.
Loopback monitoring of critical control signals is easy since the input and output circuitry are connected in tandem to each channel.
Features
- 32 digital input and/or output channels
- 0...60 VDC input range, 60 VDC low-side switch outputs
- Outputs sink up to 1 A per channel
- TTL-compatible input threshold with hysteresis
- Change-of-state/level interrupts (up to 8)
- Buffered inputs include hysteresis to increase noise immunity.
- Interrupts are software-programmable for a change of state or level detection.
- Loopback monitoring enables self-test and fault diagnostics to detect open switches or shorts.
- High impedance inputs prevent loading of the input source and minimize current.
- 0...+70°C or -40...+85°C (E version)
