6.7 I/O CARD SPECIFICATIONS

Specifications

POWER

Input:

Uses 0.57 W (supplied by MCU), excluding

power consumed by I/O channels connected to field

devices.

Analog Loop:

+T voltage from MCU (24 Vdc when

I/O Converter Card is installed; otherwise, same as

12 or 24 Vdc power to the MCU). Available at “+T”

terminal on each analog input channel.

DISCRETE INPUTS

Quantity/Type:

12 sourced discrete inputs.

Field Wiring Terminals:

“+” positive source voltage,

“-” negative input (common).

Signal Current:

0.5 to 3.5 mA in the active (on)

state, 0 to 0.2 mA in the inactive (off) state.

PULSE COUNTER INPUTS

Quantity/Type:

Four sourced pulse counter inputs.

Field Wiring Terminals:

“+” positive source voltage,

“-” negative input (common).

Signal Current:

0.5 to 3.5 mA in the active (on)

state, 0 to 0.2 mA in the inactive (off) state.

Frequency:

10 kHz maximum.

ANALOG INPUTS

Quantity/Type:

Eight, single-ended voltage-sense

(current loop if supplied scaling resistor is used).

Field Wiring Terminals:

“T” loop power, “+”

positive input, “–” negative input (common).

Voltage:

1 to 5 Vdc, software configurable. 4 to 20

mA, with 250Ω resistor (supplied) installed across

terminals “+” and “-”.

Accuracy:

0.1% over a -40 to 65 °C (-40 to 149 °F)

range.

Impedance:

One MΩ.

Filter:

Double-pole, low-pass.

Resolution:

12 bits.

DISCRETE OUTPUTS

Quantity/Type:

Six dry-contact SPST relay outputs.

Field Wiring Terminals:

“NO” normally-open

contact; “COM” common.

DISCRETE OUTPUTS (Continued)

Contact Rating:

30 Vdc, 5 A maximum.

Isolation:

1500 volts.

ANALOG OUTPUTS

Quantity/Type:

Two current loop outputs.

Field Wiring Terminals:

“+” positive output and “-”

common.

Range:

4-20 mA with 0 to 22 mA overranging.

Loop Resistance:

300 ohms maximum when +T

is 12 Vdc; 600 ohms maximum when +T is 24 Vdc.

Resolution:

12 bits.

Accuracy:

0.1% of full-scale output.

Settling Time:

100 µs maximum.

Reset Action:

Output goes to zero percent output

or last value (software configurable) on power-up

(warm start) or on watchdog timeout.

DIMENSIONS

0.5 in. D by 5 in. H by 12 in. W (13 mm by 127 mm

by 305 mm).

WEIGHT

1.75 lb. (0.8 kg) nominal.

ENVIRONMENTAL

Operating Temperature:

-40 to 70 °C (-40 to

158 °F).

Storage Temperature:

-50 to 85 °C (-58 to

185 °F).

Operating Humidity:

To 95%, non-condensing.

Vibration:

Designed to meet SAMA 31.1, Cond. 3.

Radiated/Conducted Transmissions:

Complies

with FCC Part 15 Class A.

Voltage Surge Immunity:

Designed to meet IEC

801-4 and EN 61000-4-5.

APPROVAL RATING

Approved by CSA for hazardous locations Class I,

Division 2, Groups A, B, C, and D.
