The Automated Logic OptiFlex OFX48 equipment expander increases the input and output capacity of the OptiFlex OF683XT-E2 advanced equipment controller. It adds up to 12 I/O points, consisting of eight inputs and four outputs, to support additional equipment control requirements.
The OFX48 supports configurable universal inputs for a variety of sensor and signal types, including voltage, current, RTD, thermistor, dry contact, and pulse counter inputs. Its four outputs can be configured as analog or binary outputs to control compatible devices.
Designed for flexible installation, the expander can be mounted directly to the OF683XT-E2 in a compact configuration or remotely up to 1,000 feet away. DIN rail or screw-tab mounting options and removable screw terminals simplify installation and wiring.
