RELIANCE 0-52807 Channel input card
The number of resistors connected in series depends on the resistor type. The thermal sensor is not mounted on the attached regenerative resistor. An abnormal heating of resistor may be generated at a regenerative circuit failure. Install a thermal sensor near the resistor and establish a protective circuit to shut off the main circuit power supply when abnormal heating occurs. The detection level of the thermal sensor varies according to the settings of the resistor. Set the thermal sensor in the most appropriate position on your design basis, or use the thermal sensor built-in regenerative option. (MR-RB5E, MR-RB5R, MR-RB9P, MR-RB9F, MR-RB9T, MRRB5K-4, MR-RB6B-4, MR-RB60-4, or MR-RB6K-4)
MR-J4-11KB-RZ020 to MR-J4-22KB-RZ020
MR-J4-11KB4-RZ020 to MR-J4-22KB4-RZ020 (when using the regenerative option) MR-J4-11KB-RZ020 to MR-J4-22KB-RZ020/MR-J4-11KB4-RZ020 to MR-J4-22KB4-RZ020 servo amplifiers are not supplied with regenerative resistors. When using any of these servo amplifiers, always use the MR-RB5E, MR-RB5R, MR-RB9P, MR-RB9F, MR-RB9T, MR-RB5K-4, MR-RB6B-4, MR-RB60-4, or MR-RB6K-4. Cooling the regenerative option with cooling fans improves regenerative capability. G3 and G4 are terminals for thermal sensor. Between G3 and G4 is opened when the regenerative option overheats abnormally.
