This article describes the CHESTER-C1 carrier board.
Module Overview
CHESTER-C1 is a carrier board for CHESTER-M implementing:
- 4x digital/analog inputs terminal
- 2x power relay
- RS-485 interfaces terminal
- Two 1-Wire terminals
- DC/DC converter
- Battery holder for 4x C-cell sized 3.6V batteries
CHESTER-C1 fits with the Takachi WP20-28-5Cx enclosure.
Technical Specification
- Input DC voltage range (VIN): 8-36 V
- Supported C size battery: 1 x Saft LSH14 or 1 x Saft LS26500*
- Up to 4 x C size or 3 x D size battery on request (Saft LSH20 or LS33000)
- Nominal battery voltage: 3.6 V
- Battery idle current consumption <2 μA (without CHESTER-M)
* Saft LS26500 cannot be used with CHESTER-M-E variant (without supercapacitors).
