Power Supply Terminals Power is supplied to the 8-point controllers through the DC+ and DC– terminals.
Connect the DC+ terminals to 24 VDC; the DC– terminals to 0 VDC. The rated
voltage (21.6 to 26.4 V) must be supplied to the DIN connector on the E5ZD;
these are not switching power-supply terminals.
To ensure activation of the power supply, it is necessary that at least twice the
rated current capacity be available when power is turned on.
Memory Bank Terminals The BANK0, BANK1, BANK2, and three ING terminals can be used to select the
memory bank to be used for temperature control. Refer to
Section 3-3 Memory
Banks for operational details. The BANK0, BANK1, and BANK2 terminals are
activated by connecting each to a ING terminal. The terminals can be connected
either through contacts, e.g., relays, or through transistors or other no-contact
devices. The memory banks designated by the various open-closed combina-
tions of these terminals are shown in the following table.

Control Outputs The control outputs can be wired for independent use as voltage outputs or as
open-collector outputs. In either case, a diode must be included in the output cir-
cuit to protect the Unit’s internal circuits.
