16 Channel Isolated AC Digital Inputs (0-132 VAC) (Part# 8511)
The SeaRAQ 8511 expansion board adds 16
channels of isolated digital inputs rated for 0-
132 VAC.
16 Isolated Digital Inputs 4 Form C Relay Outputs (Part# 8512)
The SeaRAQ 8512 expansion board adds 16
channels of isolated digital inputs rated for
24VDC and 4 Form C Relays.
16 Channel Isolated Relay Outputs (Part# 8520)
The SeaRAQ 8520 expansion board adds 16
isolated relay outputs rated for 5-250 VAC and 5-
30 VDC. The Form A relays are organized into
four banks of four relays, with each bank sharing
a common. The relays support a maximum
current load of 2A per relay (4A maximum per
bank). The SPST relays are normally open and
close when energized.
8 Channel Isolated Relay Outputs (Part# 8521)
The SeaRAQ 8521 expansion board adds 8
isolated relay outputs rated for 5-250 VAC and 5-
30 VDC. The Form A relays each have a discrete
common and support a maximum 4A current
load. The SPST relays are normally open and
close when energized.
8 Channel-to-Channel Isolated Analog Inputs (Part# 6510)
The SeaRAQ 6510 provides eight general
purpose 16-bit A/D channels that can be
individually configured for 4-20 mA current loop,
0-5V or 0-10V voltage inputs.
8 Channel-to-Channel Isolated Analog Outputs (Part# 6520)
The SeaRAQ 6520 expansion board adds eight 4-
20 mA current loop transmitter outputs and is
ideal for interfacing a wide variety of industrial
process control and test equipment that use 4-20
mA signaling.
