Process Applications |
N/A
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 or other logic devices. |

Single Pole Double Throw (SPDT) Relay Output |
N/A Control output relays are included for each set-point. During operation, the relay is energized once the milliamp 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 at 115 Vac. |
Adjustable Deadband Range |
N/A An integral deadband is selectable for the set-point values offering up to 12.5 % F.S. adjustability. This deadband is adjustable for the set-points as a group (i.e., not independently adjustable for each set-point). The MultiPoint Process Switch is factory preset with a nominal 1% F.S. deadband. |
Automatic Overload Reset |
N/A This unit features protection against input circuit overloads and automatically resets when current level drops. Using advanced PTC resistor technology, the protection circuit trips whenever the signal input current exceeds 70 mAdc. |
Input Current Limiting |
N/A
A positive temperature coefficient (PTC) resistor circuit is incorporated into the Process Switch for protection against overcurrent situations. This thermal resistor undergoes increased orders of magnitude in resistance when an input current ≥ 70.0 mAdc heats it above a certain point. In the switched state, a latched high-resistance limits current to no more than a few milliamps. The resistor circuit resets automatically, permitting normal current flow once the input drops below 70 mAdc. (NOTE - Protective resistor circuit is rated for 30 trip/cycles max.) |
4 to 20 Milliampere (mA) Input Signal |
N/A
The 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 input range. The Process Switch accepts any proportional, externally-powered two-wire 4-20 mAdc current loop from any typical process transmitter (level, pressure or temperature). Unit must be wired in series with transmitter to maintain proper polarity at the + and - terminals. Internal input resistance of the Process Switch is 132 ohms (nominal) during normal operation. |
Adjustable Set Points |
N/A
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" adjustments and output relays. When illuminated, the LED indicates that the set-point has been reached and corresponding relay energized. |
Single Pole Double Throw (SPDT) (Form-C) Output Relays |
N/A
Four (4) independent SPDT (single-pole/double-throw) relays are provided on the Process Switch. Form-C configuration includes normally-open (N.O.), normally closed (N.C.) and common (C) relay contacts. Rated for 3.0 Amps maximum at nominal 115 Vac. Relay is energized when corresponding set-point milliamp value is exceeded. |
Additional Information |
N/A 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. |
