LogiStat

NOTE A LogiStat sensor connected to the ZN551 uses IN-4 and IN-5. An RS

room sensor connected to the Rnet port does not use these inputs.

You can wire an RS Standard, RS Plus or RS Pro to the ZN551's Rnet port.

Or you can wire a LogiStat or LogiStat Plus to the ZN551's LStat port. See the

RS Room Sensors Technical Instructions (http://info.automatedlogic.com) or

the LogiStat Sensors Technical Instructions (http://info.automatedlogic.com).

NOTE The ZN551 does not support the LogiStat Pro.

The ZN551 has 5 digital outputs. You can connect each output to a

maximum of 24 Vac/Vdc. Each output is a dry contact rated at 1 A, 24 V

maximum and is normally open.

The ZN551 has 1 analog output that supports voltage devices from 0-10 Vdc.

The controlled device must have a minimum of 2000 Ohms resistance

Description

Precon type 2 (10 kOhm at 77°F). Input voltages will be

from 0.33 Vdc to 2.52 Vdc for thermistors.

A 3.3 Vdc wetting voltage detects contact position,

resulting in a 0.3 mA maximum sense current when the

contacts are closed.

The output impedance of a 0–5 Vdc source must not

exceed 100 Ohms. The input impedance of the ZN551

is approximately 30 kOhm.

IN-4–See Thermistor.

IN-5–Setpoint adjust. Input voltages should be from

1.4–3.4 Vdc.
