● E5ER
Note: Do not use the output from an Inverter for the power supply.
*1. When ordering, specify the power supply. Different models are used for 100 to 240 VAC and 24 VDC/AC.
*2. Multi-input. Switch between temperature and analog input using the input type switch.
Basic insulation is provided between the power supply and input terminals and between the power supply and output terminals.

104 DeviceNet Communications Unit for Modular Temperature Controller EJ1-DRT
DeviceNet Communications Unit for Modular Temperature Controller
EJ1-DRT
Easily Perform Temperature Control
for Multiple Channels.
• Up to 16 Temperature Controllers can be connected to a single DeviceNet
Communications Unit.
• Sharing target values and present values using remote I/O communications
without special programming reduces development work for communications.
• Flexibly allocate I/O memory using either fixed allocation addresses for simple
allocations or user-set allocations from the Configurator.
• The EJ1 parameters can be backed up for easy resetting of parameters when the
EJ1 is replaced.
• Explicit messages be sent from the PLC to easily read or write any parameter.
Ordering Information
● DeviceNet Communications Unit
● Modular Temperature Controller
*1. An End Unit is always required for connection to a Basic Unit or an HFU. An HFU cannot operate without a Basic Unit. External communications cannot be performed when
using a Basic Unit only.
*2. For heating/cooling control applications, control outputs 3 and 4 on the 2-point models are used for the cooling or heating control outputs.
On the 4-point models, heating/cooling control is performed for the two input points.
*3. When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately.
