Effective: March, 1997 (replaces October, 1995) Supplment 1400-10 mg\e Channel Analog Set-Pomt Contro ■ 4 Adjustable Set Points ■ Simple Control Process Functions ■ Independent SPDT (Form C) Relays ■ For Process Transmitters with 4-20 mA Output Multi-Point Process Switch is a single channel analog set-point control. It provides continuous monitoring of a typical process loop with four (4) independent set-points that are user adjustable over the full range. The process Switch may be used in conjunction with any process transmitter (i.e., pressure, level, temperature) that incorporates a two-wire, 4-20 mA output. SPDT Relay Output Control output relays are included for each set-point. During operation, the relay is energized once the mil-liamp value is exceeded. Both normally-open (N.O.) and normally-closed (N.C.) contacts are provided with the Form-C type relays. These SPDT relays are rated 3.0 Amps @ 115 Vac. Adjustable Deadband Range An integral deadband is selectable for the set-point values offering up to 12.5 % F.S. adjustability. This dead-band is adjustable for the set-points as a group (i.e., not independently adjustable for each set-point). The Multi-Point Process Switch is factory preset with a nominal 1% F.S. deadband. Automatic Overload Reset This unit features protection against input circuit over-loads and automatically resets when current level drops. Using advanced PTC resistor technology, the protection circuit trips whenever the signal input current exceeds 70 mAdc.

Multi-Point Process Switch Supplement 1400-10 Process Applications 4-20 mA Input Signal The Process Switch can be used to control continuous process operations, provide fail-safe limiting or alarm functions. In a level application, the switch can be used to actuate pumps, outlet valves or even to initiate CIP cycles. The Multi-Point Process Switch can monitor process variables within any industrial control environment. MULTI-POINT Process Switch offers greater accuracy than conventional alarm trips. Monitors and triggers simple process functions more easily as compared to PID controllers, PLCs...

User Set-Points LED Status Indicators Adjustable Set-Points The Process Switch has four (4) user set-points that can be adjusted to control continuous process operations, provide fail-safe limiting or alarm functions. Front Panel - LED Status Indicators are located on the front panel of the Process Switch. Each of the four (4) LEDs correspond to "SET1, SET2, SET3, SET4" adjust-ments and output relays. When illuminated, "rie LED indicates that the set-point has been reached and corresponding relay energized.
