Note:
1.When using the heater burnout alarm function with a standard model, the Linear Output Unit cannot be used for the control outputs (heat).
2.Be sure to specify the Current Transformer, Output Unit, and Option Unit when ordering.
3.The Digital Controller provides transfer outputs at 4 to 20 mA for the PV and other values and control outputs at 4 to 20 mA for the current outputs.
| Description | Model | Specification |
| Output Unit | E53-R | Relay |
| E53-S | SSR | |
| E53-Q | Pulse (NPN) 12 VDC | |
| E53-Q3 | Pulse (NPN) 24 VDC | |
| E53-Q4 | Pulse (PNP) 24 VDC | |
| E53-C3 | Linear (4 to 20 mA) | |
| E53-C3D | Linear (0 to 20 mA) | |
| E53-V34 | Linear (0 to 10 V) | |
| E53-V35 | Linear (0 to 5 V) |
Note:The Digital Controller uses a dedicated, high-resolution Output Unit. The E53-C Current Output Unit for the E5[]X cannot be used with the Digital Controller.
| Description | Model | Specification |
| Option Unit | E53-AKB | Event input |
| E53-EN01 | Communication (RS-232C) | |
