ST46-IN1KAR.112
Controller for cooling applications
Order number 900237.030
As of: 26.01.2017, Software V1.0
Wiring diagram
Product description
The controller ST46-IN1KAR.112 is intended for the assembly on DIN rail, which allows easy installation in the
switch gear cabinet. It has two analogue inputs for PTC sensors and four switching exits. The functions of the re-
lays can be freely selected, whereas various applications with only one controller are possible. The controller, for
example, can operate with two coolers if the evaporator sensor is parameterized as sensor for a second refrigerat-
ing chamber. The LEDs indicate the status of the control exits. The controller is supplied with 230V AC.
Networking of the controller takes place via ST Bus interface.
Sensor: PTC
Range: - 50 ... 130 °C
Housing size (L x W x H): 95 x 53 x 59mm
Installation: Clip-on mounting on DIN-Rail 35 x 7,5mm
Connector: screw terminal

Page 4: General Information
GENERAL INFORMATION CONTROL KEYS The ST……112 controllers are designed for general use in refrigerating plants. Depending on the existing hardware, up to four temperature sensors can be connected. These can either be used for capturing the cold store temperature, evaporator temperature, super-frost core temperature, the temperature of a second control circuit or the temperature of the condenser. -
