West 6700+ Temperature Controller. The 6700+ limit controller is a member of the Plus Series family. The instrument provides a latched relay output which is activated when process value either exceeds or falls below the pre-set limit level. The output provides a fail-safe cut-off which has to be reset before the process can continue. The LED indication shows when limits have been exceeded and when the relay is latched out. A full range of universal sensor input options allow the 6700+ to provide a valuable control 'watchdog' for most systems. 5A Latching Limit Relay as standard Easy to use HMI Configuration via PC/Customisable operator menu Auto-hardware detect/set-up Modbus communications Jumperless configuration Process alarms Optional digital input and remote reset Optional 10 V SSR driver output Backward compatible panel cutout, housing and terminal wiring capability FM approval
