Figure 5. T6050 Simplified Schematic
The additional guidelines below should be followed when wiring the T6050:
•
The stripped portion of the wires should be 5/16” (8 mm) long.
•
Wires should be inserted in the clamp type terminals until they touch the internal stops.
The terminal screw should be tightened while holding the wire in place. Check for
proper clamp pressure with a gentle tug on the wire.
Two-Wire Loop Power Wiring
•
The T6050 two-wire LOOP POWER IN + should be 22-32VDC.
•
The two-wire Loop Power current requirments are 45 mA surge maximum at power up, 2
mA + Analog Output Value (20 mA maximum) equals 22 mA maximum after power up.
•
The two-wire Loop Power power requirments are 1.44 watts surge maximum at power
up, 0.7 watts maximum after power up.
Wiring Note 1: Due to the 45 mA current surge maximum at power up, the 22-32 VDC Loop Power
In + at the T6050 SurgeGard™ Terminal 5 should be from a source that does not limit the current
below 50 mA.
