E53A4A1N DANAHER

1/2 inch Graphic Dot Matrix Backlit LCD With Multiple
Language Capabilities
• Menu-Guided Operation
• Simple Interactive Diagnostics
• Password-Protected Access
• Universal Mounted, Epoxy Coated Aluminum 1/2 DIN,
NEMA 4X Enclosure
• (2) 0/4-20 mA Outputs and (4) Relays
The Model 53 Controllers are best suited for applications requiring
environmental ratings, high level of control, and multiple 0/4-20 mA
and relay outputs. The Model 53 features a easy to follow clear text
driven menu and is equipped with four electromechanical relays;
SPDT (Form C) contacts; UL rated 5A 115/230 Vac, 5A @ 30 Vdc
resistive. The controllers are housed in a 1/2 DIN, NEMA 4X
enclosure and include hardware for panel, surface or pipe mounting.
