Relay Control

Relay Control -- Introduction

Two-position control, using a digital (relay) output, is used to turn something on and off. We use a differential and an offset to tell an output when to open and close based on the control variable and setpoint.

Relay Control -- Definitions

• Differential – amount of change in the control variable from when the output turns on to when it turns off

• Offset – a value that creates a deadband for a stage – the first stage typically has an offset of 0

Proportional Control

Proportional Control -- Introduction

Analog outputs are called modulating outputs. These outputs vary based on how far the input is away from setpoint. Modulating outputs provide tighter control than two position outputs.

Proportional Control -- Definitions

• Proportional Control – generates an output that is related to the distance between the active setpoint and the input

• Proportional Band/Throttling Range – number of degrees (or percent of span) that the input must change to drive the output from 0 to 100% (either 0 to 20 mA or 4 to 20 mA)


• Setpoint Offset – a value that creates a deadband before modulation starts

• Aquastat – allows the action to reverse when a digital input is made (SZ1017a,

SZ1018, SZ1143b, SZ1051) or an analog input exceeds a certain value (SZ1025a, SZ1018, SZ1062, SZ1064)


• Direct Acting – the output increases as the input increases

• Reverse Acting – the output decreases as the input increases

Direct Acting - Output 12mA @ Setpoint

Reverse Acting - Output 12mA @ Setpoint

Direct Acting - Output 4 or 20mA @ Setpoint

Cooling Heating

Reverse Acting - Output 4 or 20mA @ Setpoint
