The 6700+, 8700+, and 4700+ limit controllers are members of the P series family. These instruments provide a latched relay output which is activated when process value either exceeds or falls below the a pre-set limit level, providing a fail-safe cut off which has to then be reset before the process can continue. The LED indication shows when limits have been exceeded and when the relay is latched out.
With a full range of universal sensor input options, the 6700+, 8700+, and 4700+ provide a valuable control ‘watchdog’ for most systems. Features include: high or low trip points, 5 amp latching limit relay, remote reset option, exceed & relay indicators, jumperless configuration,  auto detection hardware, modbus & ASCII comms, two annunciators or alarms,  available in 1/16, 1/8 & 1/4 DIN formats.
