DUAL CHANNEL RTD DIN RAIL
PUSH BUTTON TEMPERATURE TRANSMITTER SEM523P

The simple push of a button ranges and calibrates the SEM523P transmitter.  There is no need for jumpers, potentiometer adjustments or a computer.  Ease of re-ranging assures you will have the range you need in stock.

High accuracy, stability, and flexibility at a very attractive price make the SEM523P the transmitter of choice for many applications.  The SEM523P provides a level of performance superior to analog units at comparable price.

CALIBRATION PROCEDURE:

1. Connect an RTD simulator/calibrator to the input and between 8 & 30 volts DC to the output of the SEM203P.
2. Set the simulator to the desired temperature at 4 mA.  Press and HOLD the calibration button until the LED starts to blink.
3. Set the simulator to the desired temperature at 20 mA.  Press the calibration button and release.  The LED continues blinking and then shuts off confirming that the unit is calibrated.

It's that simple and that fast.

DM3430 Series

TRUE RMS CURRENT AND VOLTMETER FOR AC AND DC
DM3430 Series

It is highly accurate and designed to measure AC or DC voltages up to 550 Volts or currents up to 6 Amps.  Readings can be displayed as current or voltage or, alternatively, the reading can be easily scaled from the front panel to take into account a multiplier from a transformed input or to display directly in engineering values.  The 3.5KV isolation gives added protection when the instrument is used to measure high voltages.  This is particularly important when measuring current, in that the instrument can be mounted anywhere in the measuring circuit and remains unaffected by any standing voltage.

The DM3430 has a number of special software features including Peak and Valley memory (Storing Maximum and Minimum readings) and an Alarm Inhibit that disables the alarm function for a programmable period after start up.  It is available with a choice of two power supplies, S1 for 90-253 VAC, or S2 for 20-35 VDC.

Output functions including dual relays, 4-20 mA retransmission or Modbus RS485 serial communications.  Options are all available and easily installed without dismantling the case thanks to the unique "plug and play" option pod design.

All programming is done via a simple to use menu accessible from the instrument front panel or via the RS-485 Modbus RTU serial communications option.

PUSH BUTTON THERMOCOUPLE
TEMPERATURE TRANSMITTER
SEM203TC

The SEM203TC is available in three versions, each accepting a choice of three different thermocouple types.  An on board LED indicates the successful completion of ranging, TC selection and provides indication of sensor health.

Thermocouple Selection

1. Depress and hold button down and then apply power to the unit.
2. Release button.
3. Depress button one, two or three times to select specific thermocouple type. ( Model dependant.  For Model SEM203TC-1: once for "K", twice for "J", three times for "T").  The LED will blink with each depression.  After several seconds the LED will flash the number times corresponding to the TC selected.

Ranging

1. Connect a thermocouple simulator to input and a 24 VDC power supply to output.
2. Set the simulator to the temperature desired at 4ma. Press and HOLD the button down until the LED starts to blink.
3. Set the simulator to the temperature desired at 20ma. Press and release the calibration button. The LED blinks and then stops, confirming the unit is calibrated.
