Part Number : HTP-SC32
Nhà sản xuất : MTL Instruments
Product type : HART connection unit
Integrated connection
As a simple solution for handling the HART maintenance signals passing to and from the field devices the HTP-SC32 will often be the primary method of choice. It is intended for analogue input signals but may also be used for analogue outputs if the host system is compatible with HART communications.
Able to handle up to 32 channels through its screw-clamp field and system terminals, it is a convenient way to integrate HART maintenance facilities. The HTP-SC32 provides a selfcontained solution because the MTL4850/54 HART multiplexer is already on-board and requires only DC power and a simple RS485 link to the host management PC to get started.
Two terminals are provided for each channel enabling connections to be made to 2-wire transmitters, 4/20mA current loops or voltage inputs. Each channel is isolated so it may be connected to any suitable point in the analogue loop, and input and output types may be mixed.
HART signals have to be terminated into an impedance of >240 , so provision is made on the circuit board to fit parallel resistors – normally 250 – or a series resistor if the input impedance at the point of connection is <240 .
no parallel resistor, zero ohm link fitted in series (used for current inputs with 250 input impedance or HART compatible outputs)
