CompactPCI Systems

Introduction

The MIC-3761 relay actuator and isolated D/I card is an add-on card for the PCI bus. It provides 8 opto-isolated digital inputs with isolation protection of 3,750 V

for collecting

digital inputs in noisy environments, and 8 relay actuators for serving as ON/OFF control devices or small power switches. For easy monitoring, each relay is equipped with one red

LED to show its ON/OFF status. The MIC-3761’s eight optically-isolated digital input channels are ideal for digital input in noisy environments or with ﬂoating potentials.

Rugged Protection

The MIC-3761 digital input channels feature rugged protection for industrial, lab and machinery automation applications. It durably withstands voltage up to 3,750 V

, protecting

your host system from any incidental harms. If connected to an external input source with surge-protection, the MIC-3761 can offer up to a maximum of 2,000 V

ESD (Electrostatic

Discharge) protection. Even with an input voltage rising up to 70 V

, the MIC-3761 can still manage to work properly for a short period of time.

Reset Protection Fulﬁlls Requirement for Industrial Applications

When the system has undergone a hot reset (i.e. without turning off the system power), the MIC-3761 can either retain output values of each channel, or return to its default conﬁguration

as open status, depending on its on-board jumper setting. This function protects the system from unwanted operations during unexpected system resets.
