Product discontinuation:
The temperature controllers, of the T48 series, have been discontinued as of 01.07.2018. Therefore, only the devices listed below are still available. If the device you are looking for is not available, please contact our application consultants. We will be happy to advise you on alternatives.
This small temperature controller is an all-rounder. Equipped with a newly developed Thermo-ASIC, modern programming, operating and control technologies are implemented in a housing designed for harsh industrial use. Everything has been done to ensure that the T48 is quick to commission, easy and safe to operate and performs its task efficiently for many years. Finally, superior functionality ensures simple adaptation to all conceivable control tasks. The process parameters can be determined via self-optimization and then easily modified. The operator is continuously informed of the actual value. The second display allows the setpoint, percentage output or deviation to be displayed at the touch of a button. The T48 has a newly developed calculation algorithm, with which the target value is approached particularly quickly and overshoot is minimized. The output board can be changed quickly and easily.

Power supply
AC version: 85 - 250 VAC, 50/60 Hz, 8 VA.
DC version: DC: 18 - 36 VDC, 7 W; AC: 24 VAC, 50/60 Hz, 9VA.
Housing
Flame- and scratch-resistant black plastic.
Rear panel is mounted on the control panel, front panel can be pulled out. Devices can be mounted directly next to each other.
Dimensions: W 50 x H 50 x D 106 mm. Panel cut-out DIN W 45 x H 45 mm. Mounting via mounting frame with clamping screws.
Ambient temperature: Operation: 0°...+50°C, storage: -40° to +80°C.
Accessories
Solid-state relay: Is connected to the SSR driver output and switches 50 to 280 VAC (nominal 240 VAC) at max. 45 A (35 A at ambient temperature = 50 °C).
Dimensions: W 140 x H 120 x D 66 mm (incl. heat sink).
Spare boards: Spare output boards equipped with 1 or 3 relays/SSRs. The basic version includes a control output for two-point control with P, I, PI, PD and PID behavior. The output is time-proportional.
Outputs
Relay output: NO contact, 3 A at 250 VAC or 30 VDC (resistive load).
75 VA at 120 VAC (inductive load).
SSR driver output: 45 mA at min. 4 V nominal 7 V.
Alarm outputs: 1 or 2 NO contacts with common ground, 3 A at 250 VAC or 30 VDC (resistive load) 75 VA at 120 VAC (inductive load).
Second control output (cooling): programmable instead of the 2nd alarm output: with P, I, PI, PD and PID behavior.
Analog output: freely scalable, 0 - 20 mA, 4 - 20 mA or 0 to 10 V with a resolution of 3500 steps.
Second analog output: refers directly to the input signal.
Heating current monitoring: 100 mA AC from e.g. current transformer (see accessories), 50 - 460 Hz, galvanically isolated.
Serial interface: RS485, 32 devices can be networked, max. baud rate: 9600.
2nd analog input, setpoint specification: 0/4 - 20 mA, freely scalable, for external setpoint specification or cascade control with 2 control loops.
