BTC-901 Analog Temperature Controller
Compact 1/16 DIN control with relay alarm output
BTC-901 is a cost-effective analog temperature controller in a 1/16 DIN (48×48mm) compact housing. Designed for simple and reliable control, it features an easy-to-use analog dial, ON/OFF or time proportional control, and relay alarm output. With support for thermocouple or RTD input, BTC-901 is ideal for applications requiring stable, low-cost temperature regulation in compact panels.
BTC-901 Front Panel and LED Indicators
Clear LED status indicators with analog dial control
The BTC-901 features a compact 48×48mm panel with a front-mounted analog potentiometer dial for setpoint adjustment. Two LED status indicators provide instant feedback: red for output ON and green for output OFF. This simple interface enables users to quickly monitor control status and adjust the temperature without complex menus or digital setup. It’s ideal for operators who prefer tactile controls in industrial environments.
Supports thermocouple and RTD sensors with accuracy
BTC-901 accepts inputs from thermocouple (Type J or K) or RTD PT100 (DIN or JIS) sensors. Sensor type and range are selected via internal jumper settings. The controller ensures accurate measurement performance with cold junction compensation for thermocouples and stable RTD signal processing. This flexibility makes BTC-901 suitable for various heating and temperature monitoring applications.
Relay or SSR output with built-in alarm relay
Relay, SSR voltage and alarm relay outputs available
BTC-901 provides multiple output formats:
-
Relay contact output (5A @ 250VAC)
-
SSR voltage drive output (12VDC, 20mA)
Users can select between ON/OFF control or time proportional control by jumper. Additionally, a deviation alarm relay output is included to provide alert signals when temperature exceeds the configured tolerance.
