Temperature Controller SA200 General Description The SA200 is a high performance 32nd DIN controller that has been specifically designed for applications where panel space is critical. Though small in size, this controller has exceptional features such as dual display of process and set value, mounting flexibility, advanced self-tuning, alarms and MODBUS communications. Features 1/32 DIN size with dual display 4-20mA output for control/retransmission Dual setpoint PV ratio, Peak/Bottom hold, Ramp-to-setpoint 1 Loop break alarm and temperature alarms Digital communications 1 Contact Close vertical mounting Close Vertical or Horizontal Mounting Self-Tuning Algorithm The SA200 offers a new self-tuning feature that is initiated at start-up and when process parameters or conditions change. In these situations, the controller evaluates whether the preset PID parameters should be maintained or replaced by the latest self-tuning parameters to achieve the best control for the process. Self-tuning can be manually turned ON/OFF in the parameter setting mode. This feature is not available with the Heat/Cool control. In addition to self-tuning, the SA200 has standard autotuning (AT) so that either function can be selected to achieve optimum process control. Close horizontal mounting Two types of Dual-Display Color The SA200 has been designed with a unique mounting bracket that allows close vertical or horizontal of multiple instru-ments to save valuable panel space. However, there is a maximum of six units in either direction with this type of installation. The SA200 has a dual-display with a larger green display (PV) and small orange display (SV). Red/Red display is also available with SA201. Green Digital Communications The SA200 offers an optional RS-485 communications interface for networking to computers, PLCs and SCADA software. MODBUS or ANSI protocol can be selected. Up to 32 units, including host computer, can be multi-dropped on one RS-485 communication line. When the communication feature is selected, the external contact input is not available. For operation in severe environments or when washdown is required, the IP66 (NEMA4) rating is available for waterproof /dustproof protection.

Temperature Controller Features Loop Break Alarm and Temperature Alarms The loop break alarm (LBA) monitors and protects an entire temperature control system. The LBA detects heater breaks, thermocouple or RTD failures, short circuits, or the failure of an operating device such as a mechanical or solid state relay. When the PID computed value reaches 100% and the temperature does not respond in a set time, the loop break alarm is activated. Conversely, when the PID value reaches 0% and the temperature does not respond accordingly, the loop break alarm is turned on. In this example, the LBA uses...
