Please note: SWA-2441B PID controller has mechanical relay output. To drive Solid State Relay (SSR), please check SWA-2451B

This PID controller has a built-in timer. It is suitable for processes that require both precise temperature and time control, a very common requirement for many temperature related applications. It can be used for powder coating ovens, mushroom substrate sterilization, heat transfer printing, etc. The timer can also be used independently from the temperature control. e.g. user can use the PID for temperature control of the espresso machine and timer for the brew pump or dosing coffee grinder.
 
The  temperature control function offers three temperature control modes: PID, on/off and manual. The PID mode is useful for precision temperature control applications. The manual mode is like a dial on the stove that controls the power output independent of the temperature. It is a useful feature for controlling the boiling of water used for beer brewing process. The on/off control is suitable for devices that are not conducive to being switched too frequently such a solenoid valve or refrigerator compressor. In addition to the on/off control, when used for cooling control, this controller also offers the "Anti-Short Cycle Delay (ASd) function that further protects the compressor from over pressure start. It allows the user to set a specific minimum delay time that prohibit the compressor from starting after being turned off.
 
The timer has eight different working modes:

Three of them are related with the temperature control. The first two start the timer when temperature reaches the set point. When time is reached, it will turn on the alarm relay. One mode will also shut off the heater at the same time. In the third mode, the timer starts after the temperature reaches set point. When set time reaches, it will shut off the heater. Relay pulls in when timer starts and drops out when it reaches the set time.

The other 5 modes allow the timer to work totally independent of the temperature controller. It can be set to time delayed relay pull-in, time delayed relay drop-out, time delayed relay pull-in and drop out, repeat pull-in and drop-out, or repeat drop-out and pull-in.
 
The timer can be reset and start by a switch connected to the reset terminals without powering off the controller. The timer function can also be deactivated so that controller functions as regular 1/16 DIN dual display controller. When alarm relay is not used for timer action, it can be used as temperature alarm. The alarm can be set for high limit, low limit, deviation high or deviation low alarms.
  
Two control output configurations are offered. SWA-2441 has a 10 A relay contact output. It can be used for controlling an external contactor. It can also be used for driving a small heater or freezer directly if the current is less than 10A. 

SWA-2441B has two additional alarm relay outputs, compared to its previous model (SWA-2441/2451 only has one alarm output). User can use alarm relay 1 as timer output alarm or temperature alarm, and alarm relay 2 as temperature alarm. One example is, when temperature is too high, high temperature alarm (relay 2) will be triggered. When time is up, timer alarm (relay 1) is triggered.
