Description
The URM series of relay boards
offer system integrators an easy,
truly universal solution for
controlling hi or low current
devices such as electric locks,
lights, sirens, etc with literally ANY
type of low voltage, dry contact or
open collector input signals.
Applications
• Single or multi-zone electric lock,
lighting control, etc.
• Use low-current outputs from burglar
alarms, fire alarms, access systems,
CCTV systems, to control hi-current
devices.
• Industrial control
• Remote and internet control
• Connect normally incompatible
equipment together via the URM
interface.
Benefits
• One relay board works with all types
of equipment output drivers.
• High quality, 2 sided circuit board for
high reliability.
• Relays are fail de-energized
configurable.
Warranty
1 year parts and labor.
URM Features and Specifications
• 5 to 24vdc power input. Maximum current
draw (all relays simultaneously
energized) is 100ma for the URM-1,
400ma for the URM-4 and 800ma for the
URM-8.
• Accepts these trigger types:
Open collector or open drain
Dry contact NC or NO.
TTL or CMOS levels
Any voltage from 3.3Vdc to 24Vdc
• Polarity protected power input.
• Each channel has its own low-dropout 5
Volt regulator
• 4.7K Ohm input impedance
• 8 Amp 120VAC form C relay output.
• Jumper selectable trigger type.
• Jumper selectable Invert or buffer input
signal for each channel.
• European-style, easy terminate, input
and output connectors.
• LED status indicators for each relay.
