• On/off determination: For non-voltage contact input, contact resistance of 1 k or less
is determined as “on” and contact resistance of 20 k or more as “off.”
For transistor open collector input, input voltage of 2 V or less is determined as “on”
and leakage current must not exceed 100
A when “off.”
• Minimum status detection hold time: About 1 sec.
Contact Outputs
• Purpose: Alarm output, FAIL output, and others
• Number of outputs: 3
• Relay contact rating: 240 V AC/1 A or 30 V DC/1 A (COM terminal is common.)
Display Specifications
• PV display:
UT350: 4-digit, 7-segment red LED display, character height of 20 mm
UT320: 4-digit, 7-segment red LED display, character height of 12 mm
• Setpoint display: 4-digit, 7-segment red LED display, character height of 9.3 mm (for
both UT350 and UT320)
• Status indicating lamps: LEDs
Safety and EMC Standards
• Safety: Compliant with IEC1010-1: 1990 and EN61010-1: 1992
Approved by CSA1010
CSA1010 installation category (overvoltage category): CATII (IEC1010-1)
Approved by UL508
• EMC standards: This instrument complies with the following EMC standards (the
instrument continues to operate at a measuring accuracy of within
20% of the range
during tests):
- EMI (emission), EN61326-1: 1997+Am1: 1998
- EMS (immunity), EN61326-1: 1997+Am1: 1998
Construction, Installation, and Wiring
