Isomators SEM1200

Product catalog summary

Overview: The SEM1200 is a dual output isolator designed to provide two separate isolated 4 to 20mA current signals from a primary loop. It requires external power for the output loops and allows for minor calibration adjustments via front-panel accessible potentiometers.

Specifications:

Input Type: Current input, 2-wire loop powered, with a range of 4 to 20 mA (maximum 30 mA).
Protection: Reverse connection protection.
Voltage Drop: Maximum of 5.0 V.
Output: Two 4 to 20 mA current sink outputs at 15 V DC.
Loop Voltage: 5 to 32 V DC, reverse protected, with specific load requirements based on voltage and ambient conditions.
Connection: Captive clamp screws, supporting cable sizes up to 4 mm sq solid or 2.5 mm sq stranded.
Case Material: Grey Polyamide, flammability rated to UL94-VO VDE 0304 Part 3, Level IIIA.
Dimensions: 60 x 75 x 12.5mm, with a mounting height of 67.5mm above the rail.
Mounting: Snap on "top hat" rail (DIN EN 50022-35).
Isolation: 500 V DC, flash tested at 1 kV, using opto coupler/transformer method.
Electrical Safety: Complies with BS EN61010-1, Pollution Degree 2, Installation Category II, Class I.
Ambient Conditions: Operates between 0 to 70ºC and 10 to 95% RH non-condensing.
Accuracy: ±0.05% (±0.008 mA) of full range output.
Stability: 0.01% per ºC.
Response Time: Less than 100 ms to reach 70% of the final value.
EMC: Tested to BS EN 61326.
Adjustments: Zero and Span Adjustment available for each channel.

Key Features: The SEM1200 provides reliable isolation and signal splitting for industrial applications, ensuring accurate and stable performance across a range of environmental conditions. It is designed for easy installation and adjustment, making it suitable for various industrial settings.
