X-19s™ | 16 Relay, 16 Digital and 4 Analog Input Expansion Module
The X-19s expansion module has 16 relays, 16 digital inputs, and 4 analog inputs which can be controlled and monitored using an X-400 or X-600M controller.
Overview
The X-19s™ expansion module is used with an X-400 or X-600M controller. The X-19s has 16 relays, 16 optically-isolated digital inputs, and 4 analog inputs. Screw terminal strips provide connections to the relays and inputs.
The X-19s is suitable for use in many applications from security systems to industrial controls where a high I/O count is required. It can be used to monitor freezer doors, light switches, and pulsed flow meters as well as control moderate loads such as solenoid valves, and lights.
Since the X-19s functions as a slave device to the X-400 or X-600M controller, the advanced features of the controller can be utilized with this module. For example scheduling, remote relay control, logging, counting, email alerts based upon single input state change or multiple input state changes, analog slope and offset calculations, and many other features are available. Attach multiple X-19s modules or a combination of expansion modules to the X-400 or X-600M for an I/O combination that is tailored to your specific needs.
Other expansion modules with different I/O combinations are also available.
