1~DESCRIPTION.
The SEM1605THV is a cost-effective digital rail mount transmitter that accepts
Thermistor temperature sensors and converts sensor output over a configured range
to a standard industrial (0 to 10) V transmission signal.

4~INSTALLATION AND WIRING
Important safety requirements
This equipment is suitable for environment Installation BS EN61010-
1 Pollution Degree 2; Installation CAT II; CLASS I and is classed as
"PERMANENTLY CONNECTED EQUIPMENT". The equipment is
intended for industrial and commercial application only and not
suitable for domestic or medical use.
The equipment must be mounted inside an enclosure that provides
protection >= IP65. In NORMAL USE, the equipment will only be
accessed for maintenance by qualified personnel. Please ensure the
equipment is mounted vertically with terminals (7 and 8) at the
bottom. This will provide maximum ventilation. This equipment may
generate heat. Ensure the enclosure size is adequate to dissipate
heat. Be sure to consider any other equipment inside the enclosure.
The equipment surfaces may be cleaned with a damp cloth. Use a
mild detergent/water. Ensure the supply is OFF before cleaning and,
on completion of cleaning, the equipment is completely dry before
the supply is turned back ON.
This equipment must be installed by a qualified person. All electrical
wiring must be carried out in accordance with the appropriate
regulations for the place of installation.

4.1~MECHANICAL.
Dimensions in mm
The equipment must be mounted on a DIN rail style DIN EN50022
inside a plastic or metal enclosure with a protection level >= IP65. All
wiring must be secured. Maximum cable sizes 2.5 mm². Connection
is via screw clamp terminals.
4.2~ELECTRICAL
CONNECTIONS. For wiring connections refer to the side label on the
SEM1605THV and this document
4.2.1~OUTPUT: connections for cable length >3 metres, use
screen or twisted pair cables.
Always ensure the output (0 to 10) V is grounded at one point; this
would normally be at the monitoring equipment or power supply.
Screened wires are recommended for output wires. Avoid running
signal wires alongside mains or AC power lines or other sources of
electrical interference.
Pin 1 = Supply 0 V (-)
Pin 2 = Supply Positive V (+), (15 to 30) Vdc
Pin 4 = Output Signal (0 to +10) V
4.2.2~INPUT
length and type and as short as possible.
Note: Tested with 30-metre input sensor wires to
meet BS EN 61326, keeping cable within this length
is recommended.
2 Wire Thermistor and RTD sensor connection
Pin 5
Pin 7
Thermistors polarity is not required.
If no sensor (input) connection is made, the transmitter will go to its
error signal output value, depending on configuration.
4.3~S LED (STATE)
The State LED is OFF under normal run conditions indicating an in-
range input signal. If the input signal is out of range or is lost, the
State LED will light (RED)
The State LED also has some programming functions. See 5.2
