What is the difference between GIC 151D12B and 47A3D412?

151D12B is a 48 x 48 mm panel mounted PID temperature controller with relay outputs. 47A3D412 is a DIN rail PT100 temperature control relay with one relay output and two 0 to 10 V DC analogue outputs.

Which GIC temperature controller should be used with a PT100 sensor?

47A3D412 is specifically listed as a PT100 temperature control relay. 151D12B is better suited where the panel requires a front mounted temperature controller with relay control.

Is 151D12B suitable for panel door mounting?

Yes. 151D12B is a 48 x 48 mm panel mounted temperature controller, making it suitable where operator access to the controller fascia is required.

Does 47A3D412 provide analogue temperature outputs?

Yes. 47A3D412 provides two 0 to 10 V DC analogue outputs in addition to its relay output.

GIC temperature controllers for industrial control panels

Summary: GIC 151D12B and 47A3D412 are industrial temperature control products for panel builders and systems integrators. 151D12B is suited to panel mounted local temperature control, while 47A3D412 is suited to DIN rail PT100 supervision with relay and analogue outputs.

GIC temperature controllers 151D12B and 47A3D412 give panel builders two different ways to manage industrial temperature control: 151D12B is a 48 x 48 mm panel mounted PID temperature controller with relay outputs, while 47A3D412 is a DIN rail PT100 temperature control relay with relay and analogue outputs.

Both products sit within Charter Controls' Temperature Controllers range and are intended for machine, heating and process control panels where temperature needs to be monitored, switched or regulated from within an industrial enclosure.

GIC 151D12B panel mount temperature controller

The 151D12B is a GIC PID temperature controller with a 48 x 48 mm panel mounted format, universal input and three relay outputs. It is suited to local temperature regulation where an operator or commissioning engineer needs direct access to the controller fascia on the panel door.

Charter Controls lists 151D12B as a relay output temperature controller for industrial process panels. It is used for heating, cooling and process control applications where relay outputs are required for control circuits.

GIC 47A3D412 PT100 temperature control relay

The 47A3D412 is a GIC PT100 temperature control relay for DIN rail mounting, designed for panel based temperature supervision where the panel needs a switched relay output and analogue temperature signalling rather than a front panel controller.

Charter Controls lists 47A3D412 with a 24 V AC/DC to 240 V AC/DC supply range, one SPCO relay output, two 0 to 10 V DC analogue outputs, PT100 input, DIN rail mounting and a 22.5 mm housing.

151D12B and 47A3D412 comparison

Product code	Product type	Mounting	Input	Outputs	Best fit
151D12B	Panel mounted PID temperature controller	48 x 48 mm panel mount	Universal temperature input	3 relay outputs	Local heating, cooling and process temperature control where front panel access is useful
47A3D412	PT100 temperature control relay	22.5 mm DIN rail	PT100	1 SPCO relay output and 2 x 0 to 10 V DC analogue outputs	PT100 based supervision, alarm switching and analogue signalling inside compact control panels

Where GIC temperature controllers fit in industrial panels

For machine builders, 151D12B is the stronger choice where the equipment requires a visible controller on the panel door, adjustable set points and direct relay control for heating or cooling stages.

For systems integrators and process control panels, 47A3D412 is useful when the control philosophy is based on PT100 sensing, relay alarm or trip output, and analogue feedback to another controller, recorder or monitoring input.

In water and wastewater, machine building and general process control, the choice usually comes down to interface and signal requirement. Use 151D12B when the panel needs local temperature control from the controller itself. Use 47A3D412 when the panel needs DIN rail PT100 temperature supervision with analogue outputs.
