Functions
Communications according to CompoWay/F (see note) are supported and are
performed through the RS-485 interface.
Up to 16 E5ZN Temperature Controllers can be operated from the host.
Note CompoWay/F is a general-purpose serial communications-based unified communica-
tions protocol developed by OMRON. CompoWay/F uses commands compatible with
the well-established FINS, together with a unified frame format on OMRON program-
mable Controllers to facilitate communications between personal computers and com-
ponents.
Number of Control
Points
One E5ZN Temperature Controller has two channels for controlling tempera-
ture.
Input Sensor Types The following input sensors can be connected for temperature input. Both
channels will use the same type of sensor.
Thermocouple: K, J, T, E, L, U, N, R, S, B
Infrared temperature sensor type: ES1A
K (10 to 70
°C), K (60 to 120°C), K
(115 to 165
°C), K (160 to 260°C)
Platinum-resistance thermometer: Pt100, JPt100
Analog input: 0 to 50 mV
Control Output The control output depends on the model as follows:
Voltage output models (E5ZN-2Q@H03@-FLK): Pulse voltage output
Transistor output models (E5ZN-2T@H03@-FLK): Transistor output
(open collector)
Current output models (E5ZN-2C@F03@-FLK): Linear current output
Alarms • Set the alarm type and alarm value, or set upper- and lower-limit alarms.
• If necessary, a more comprehensive alarm function can be achieved by
setting the “standby sequence,” “alarm hysteresis,” and “close in alarm/
open in alarm” parameters.
Control Adjustment Optimum PID constants can be set easily by autotuning.
Event Input • The following functions can be achieved using the event input (one input
per Temperature Controller): SP selection (multi-SP, 2 points max.) and
RUN/STOP.
• The event input is used by both temperature control channels.
HBA A heater burnout alarm (HBA) is supported by pulse output models only.
