Conditioning Boards Digital I/O Signal

October 1, 2012

WinSystems (Arlington, TX) has introduced two new isolated digital signal conditioning and termination boards for applications requiring signal isolation between a computer and its monitoring/control points. The ISMTRM- RELAY has 16 independent, Single Pole Double Throw (SPDT) relays. The ISM-TRM-COMBO provides a combination of 8 optically isolated inputs, 8 optically isolated outputs, and 8 Form C relays on one board. To insure reliable connection with easy removal and insertion with field wiring, industry-standard, 3.5 mm pluggable connectors are used.

The ISM-TRM-RELAY has two signal lines, Normally Open (NO) and Normally Closed (NC) plus a Common associated for each relay. The contacts can handle 6A @ 250VAC/24VDC for applications requiring medium current capacity plus isolation.

WinSystems’ ISM-TRM-COMBO offers three different signal conditioning circuits for maximum configuration flexibility. There are eight isolated inputs that have the capability to support either an active high or active low signal from 5 to 30 volts. Every input line is optically isolated from the others and from the computer interface circuits with an isolation voltage rating that exceeds 2500V.
